Had the dyno tune today

With 'just'

- 3" Custom Cat Back Exhaust

- Pod Filter

- Hybrid 600 x 300 x 76 FMIC

- 12psi Boost

- Tweaked ECU

It made 203.5kw at the rear wheels with my 18's, is this figure way too high? Because it is still getting the dump pipe, front pipe and high flow cat put on, but still pings between 4000rpm and 5000rpm and only between there.

Could my car have internals I dont know about?!

dyno wouldn't give a flywheel figure....unless it was one of those chassis ones

i'm guessing that it's just very generous....

internals wouldn't give a higher power figure....unless you had some super high compression pistons, but i'm willing to bet money that that's not the case

also i'm guessing most of us here could get 20-30rwkw extra if our engines were pinging... if its pinging probbaly means it needs detuning a little which might drop you back a few kw, plus dyno may be out etc... as everyone else has said

well, i have 199.6rwkw in a VL with a minispool which is lighter than a skyline, you must have bald tyres because when i plant it rolling in second there aint no sideways action, unless i employ the services of "Mr Gearbox Destroyer"

odds are you could have 203rwkw but... you might be running like 13:1 a/f which isnt good and will be causing the ping. my advice, take it to a place that will let you drive away with a car that doesnt ping, you never know maybe they wouldnt mind doing a rebuild for you?

Dyno figures aren't worth the paper it's printed on, unless it's to compare "before and after" gains on the same car, preferably on the same day.

true, I once saw a stock GTR with 600rwkw.

Some dynos are very generous too....if you want to compare you really need to get it done on a day with others.

And I think everyone else has addressed the pinging problem....remember the "RB" in the engine name stands for "rebuild"

    • Hi all. So I have my GTR on the lift and have been working on it a few days and today I unpacked the frontpipe that was wrapped with heat wrap stuff, because part of it was breaking down and soaked in oil. Noticed that the pipe itself does not actually look like a Mines, despite it supposedly being a Mines. But I could not find any fronpipe online that looks exacly like his, and I don't think it is a custom one. My amateur measurement also showed the two pipes are about equal length, so maybe this is just an old version of the Mines pipe? Would appreciate insight on this by the enlightened folks. greetings from Germany
    • Yeah. If I plug the connector in and connect the vacuum lines, I assume worse case scenario is that it simply doesn't work? Yep PFC.
    • I would think that rather than attempting to perform an engine swap, with all the difficulties associated with doing so in a country where the raw materials required are harder to get hold of, I would just build the CA20 for boost, find an EFI manifold for it and either add a turbo or a supercharger. Or both. You replace one set of difficulties with a different set, but I know which would be more fun.
    • Well, a proper aftermarket ECU** SHOULD be set up to run the purge solenoid, same as the factory ECU would, so that the tank breather system continues to operate the way it is supposed to. I have no knowledge of whether the PFC (which is what I assume you mean when you say Apexi) has an output (and internal logic) to run the purge solenoid. If it does not, then given the product design intent for the PFC, which is to be a plug in replacement for the stock ECU, I would consider that a massive failing on Apexi's behalf and would be another reason to think that they were a half-arsed solution to the problem if programmable management on RBs. I would suggest that since Nistune came to market (which is a LOOOOONG time ago now) there has been no valid argument for choosing a PFC, especially if the PFC can't do things like this.   **ie, Haltach, Link, Motec, etc
    • Thanks for asking the question we were all thinking!
